Emu XL-7 & MP-7 User's Group

Does anyone know if the XL/MP-7's have the Knob Hold function that 
the Proteus 2500 has? 
hold a specific key whilst moving one of the knobs it has no effect, 
when you release the button the knobs send the values, to avoid a 
huge difference in sound if the knob is far from the initial value.

I cant find it anywhere in the manual, but i read it in a review of 
the proteus 2500....
if not maybe its a suggestion for 2.01 or sumthing?!?!?!!?
